BAR OF SLAT-IRONI BLANKS.

SPECIFICATION forming part of Letters Patent No. 252,042, dated January 10, 1882.

Q i Application filed October 13, 1879.

To all whom it may concern:

My invention relates to the manufacture of slat-iron frames for carriages, and the improvement consists in rolling blanks in continuous lengths from flat bar-iron through rolls so grooved as to bring the body of the bar to the form required for the several slats, with a thickness of metal at intervals from which to lorge washer-heads at the end of each slat in the blank. These several slats are then cut apart, heads forged in the end of each of them, bolt-holes punched in the heads, and are thus of the requisite size, shape, and configuration to be put together and make a complete slatiron frame.

In the drawings, Figure I represents a slatiron Figs. II and II I, a pair of my blanks from which the slat-iron, Fig. I, is made.

' I-Ieretofore it was customary in making slatirons for carriages to roll each piece of the slat-iron separately and then forge the head to it and roll the end out flat; and this required much time and labor, which by my mode can be in great part saved. Iroll the blank in one piece (see Fig. 111) in such a manner that several parts of it, at intervals the length of the several slats required, shall be flat or halfoval or any other desired shape, of the size suitable for slat-irons,the portions of the blank between the flat or half-oval sections containing sufficient iron to enable the manufacturer to forge two heads therefrom when the sections are cut apart, so that from any pair of these 0 blanks the blacksmith is enabled to cut the requisite slats each of the requisite length, with sufficient material at one end of each section to forge a head thereon, ready to form a complete slat-iron.

It is important that the parts of the blank between the flat sections should contain more iron in proportion to the length than the flat portion, in order that there shall be enough material to form a head sufficiently strong, 5o

Formerly it was the practice in making slatirons to use sections of rolled iron of a thickness sufficient to forma head, and after forging the same, the long end of the piece of iron was rolled down flat or oval of the required 5 5 length for the several slats in a small handrollihg machine. By the use of my blanks this hand-rolling is saved, as also the waste of material incidental to rolling each slat separately from a separate piece of iron.

What I claim as my invention, and desire to secure by Letters Patent, is

The slatiron blank bar rolled through grooved rolls to give it the shape shown in Figs. II and III, from which the several sections of a slat-iron frame are out, ready to be finished and put together to form the completed slat-iron shown in Fig. 1.

In testimonywhereof I have signed my name to this specification in the presence of two wit- 7o nesses.
